Abstract

PURPOSE:To lighten an apparatus in weight by fixing a stator, where three homopolar magnets are arranged on the same circumference, and another stator, which is opposite in polarity to the former stator and has a structure similar to that of the former, at both ends of a case and by connecting a pair of blade members composed of magnetic material through a magnetic cylinder. CONSTITUTION:A stator formed by the arrangement of permanent magnets 8a-8c, 9a-9c with an arrangement angle set at 15 deg.-120 deg. on the same circumference is attached to both ends of a case 6. The circumferential inner and outer surfaces of the magnets 8a-8c are magnetized with N and S poles respectively, and those of the magnets 9a-9c, with polarities opposite thereto. A rotating shaft 1 inserted through the case 6 is fitted with rotors 2 at both ends of the case 6. The rotors 2 are formed by the connection through a ferromagnetic material cylinder 2C of members 2A, 2B composed of three blades 21-23 obtained by working of a magnetic body. A solenoid 5 is wound around frames 71, 72 attached to the case 6 between the rotors 2. When the rotors 2 are rotated, a magnetic flux changes in each space 10 between the permanent magnets so that a voltage is generated in the solenoid 5. Thus, it is possible to manufacture a light apparatus with good efficiency.

(Problem to be solved by the invention) Therefore, conventional generators have some problems in obtaining efficient power generation, and in addition, rotating magnet type generators are difficult to increase in size due to their structure and are not easy to manufacture. It has the following problems.

The object of the present invention is to eliminate the above-mentioned problems and to make it possible to manufacture a large permanent magnet type generator with particularly high efficiency.

(Means and Effects for Solving the Problems) In order to achieve the above object, the present invention has a unique arrangement angle of 15" to 12".
Magnets with the same polarity set between 0 degrees are arranged as segments on the same circumference, and magnets with poles with different polarity are arranged as segments on the same circumference, and these two magnets are connected to a generator. A stator is formed by facing each other and fixed to the case at both ends, and a rotor made of a magnetic material is attached to the drive shaft in the center of the case, and the rotor has blade members at both ends connected by a cylinder. Shape and
The rotor is configured to rotate inside the stator,
Magnetic flux is formed through the rotating magnetic material from the stator magnets at opposite poles, and power is generated in the solenoid windings arranged to intersect with the axis of the rotor.It is easy to manufacture and produces efficient power generation with little heat generation. It can be carried out.

(Example> Next, one embodiment of the present invention will be described based on the drawings.

Referring to Figures 1 and 2, 1 is a drive shaft made of a non-magnetic material, and a rotor 2 made of a magnetic material such as pure iron or a few percent silicon steel is attached to the drive shaft 1 using a non-magnetic material. Attach via body bushing 3, etc.

As shown in FIG. 2, the rotor 2 has members 2A and 2B at both ends, each consisting of three blades 2□2t and 2s made of a magnetic material, and the blade members 2A and 2B at both ends.
are connected by a magnetic body 2C processed into a cylindrical shape.

The blade members 2A and 2B of the rotor 2 are fixed magnets (8a, 8b, 8c) and (9) of the stator, which will be described later.
a, 9b, 9c) with their outer peripheries facing each other, and the rotor 2 can rotate inside the stator.

On the outside of the rotor 2 are frames 71 and 7 attached to the case 6.
The solenoid winding 5 is arranged coaxially with the drive shaft 1 by □.

The magnets 8a to 8c and the magnets 9a to 9c are fixed to the case 6 as segments arranged on the same circumference, facing each other at both ends of one generator to form a stator.

The magnets 8a to 8C have an N pole on the inner circumference and an S pole on the outer circumference, and 1M1 stones 9a to 9c have an S pole on the inner circumference and an N pole on the outer circumference, contrary to the magnets 8a to 8c. It is magnetized.

Although each of the above-mentioned segments is shown having an arrangement angle of 120'', this arrangement angle may be appropriately set to a unique arrangement angle between 15° and 120''.

Next, the effect will be explained.

In the states shown in FIGS. 1 and 2, stator magnets ga, 1
The magnetic flux from the N poles of 3b and 9c is the blade member 2A of the rotor 2.
, the magnetic material 202 reaches the S pole of the other stator magnet 9a, 9b, 9c via the blade member 2B.

At this time, the magnetic flux intersects with the solenoid winding &i15.

Then, when the rotor starts rotating inside the stator in the direction of the arrow, stator magnets 8a, 8b, 8c and 9a, 9b, 9c
A compressive opening/closing operation of the magnetic flux occurs at each interval 10 (see FIG. 2), and this change in magnetic flux allows the solenoid winding to efficiently generate electricity.

(Effects of the Invention) This invention is as detailed above, and the N
Regardless of the magnetic flux compression between the N and S poles, the power generation effect is generated by changes in the magnetic flux density of a single pole, and by using the minor loop of the hysteresis curve, the hysteresis loss of the iron loss can be reduced. This reduces the amount of electricity generated, which alleviates the conventional noise phenomenon, making it possible to perform extremely stable and highly efficient power generation with little heat generation.

It has many features such as reduced driving torque.

Furthermore, since the rotor is structurally lightweight, it is easy to manufacture, and it is possible to manufacture even fairly large rotors, which has the advantage of being widely applicable in various industrial fields.
